' and useful Improvements in a Combined Window-Sash Hoisting and Locking Mechanism, of which the followingis a full and complete specification, such as willenable thoseskilled inthe art to which it appertains to make and use the same. y l I This invention relates to alcombined window-sash hoisting andlo'cking mechanism; and it has for its object, to provide'a simple and improved mechanism ofthis character -which will loe inexpensivein construction,

eifective in operation, and which will Obviate the use of cords or weights.`

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by the same letters of reference in each of the views, and in whichf- Figure lis a frontelevation of a portion of .a window provided 'with "our invention, the

view being takenon vthe inside and parts being Y broken away to show .the vinterior construction. Fig.v 2 is a transverse horizontal sectional .View taken'on the plane Of the Operating mechanism of the sashes; and Figs. 3, 4, and 5 are vertical transverse sectional views.,

v.ln the drawings forming part of this speciiication, A designates the window-frame, B the upper sash, and C the lower sash. The side stile or frame-bars of the respective sashes are provided at their inner opposite faces with vertical Vlongitudinal rack-bars o and c', respectively.

Intermediately'between the bottom stile Or frameebar b of the upper sash and the top stile or frame-bar Ic"v of the lower sash is mounted a transverse'rotaryshaft D, having a bearing, as at d, at one end in the'windOw-frame A, and having its Opposite end bearing, as at d', in the opposite side of the window-frame, this latter end being extended within the frame and provided with a bevel-pinion e, meshing with a corresponding gear e upon lower ends ofthe rack-bars b of the upper Y sash and the upper ends of the rack-bars c of the lower sash terminate, respectively, at a sufficient point above and below the gears F to provide a relative construction and arrangement in which the rack-bars will be out of engagement with said gears and when the window-sashes are in normal closed position. Therefore when the sashes are in normal closed positionV the shaftD and its gears will rotate without engagement with or action upon either sash.

To providev for sustaining and locking the upper sash in closed position, two oppositelyprojecting bars G G are slidably mounted within the lower stile or frame-bar Z2" of the sash and in longitudinal position with relation to the latter, the inner ends of these bars being pivotally connected by means of connecting-rods g g' `with an operating-lever H, fulcrumed in the stile b and having an Operating-handle'h, projecting therefrom at the top. The pivoted rods g g connect with the lever I-I at different sides Of the fulcrum of the latter, so that when the lever is turned upon its fulcrum the oppoSitely-projecting bars G G will be simultaneously drawn inwardly or simultaneously projected outwardly, their respective ends g2 being adapted to engage suitable receiving recesses or holes a in the respective sides of the window-frame. This bar and le ver mechanism thus serves tol lock the upper sash and sustain' the same in closed position. v

The bars G carry a'section' of la'rack, as at c', corresponding to and adapted to register with the lower ends of the rack-bars b and adapted to pass into and out of engagement with the gears F. The relative construction and arrangement are such that when the bars Gare in locked position the sections of racks.r

IOO

and out of alinement with the rack-bars l1', so that any rotation of the shaft D and its gears will effect no operation of the upper sash; but when the bars G are moved into unlocking position and from engagement with the recesses a by operation of the lever H the rack-sections i will be brought into register' ing position with the rack-bars Z1 and into engagcment with the gears F, so that rotation of the shaft D will then operate the upper sash.

XVe provide in the top stile or frame-bar c" of the lower s( sh a corresponding arrangement of slidable bars K K with their pivotal connecting-rods 7a' 7a', connecting with an operating-lever L. These bars K K maybe arranged to slide into locking engagement with holes or recesses in the window-casing in the same manner as the bars G G of the upper sash; but inasmuch as it is not necessary to sustain or support the lower sash in closed position said locking connection may be dispensed with, the bars K K being under these circumstances simply designed to carry racksections Zinto and out of engagement with the gears F and into and out of alined position with the rack-bars c of the lower sash. 3y means of its slidable bars carrying the rack-sections and connected with the operating-lever mechanism the lower sash may be locked into engagement with the rotary shaft D and its gears or disconnected therefrom, so that said shaft will revolve without operating the lower sash.

From the foregoing description, taken in connection with the drawings, it will be understood that the upper sash can be locked and sustained in position independently of the rotary shaft D, or it can be unlocked from sustained position and brought into engagement with said shaft, while the lower sash can be engaged or disengaged from the rotary shaft D, the independent and respect-ive operation of the upper and lower sashes being thus permitted.

The upper and lower sashes are raised or lowered simultaneously or independently by means of the rotary shaft D and its gears, the relative operations being governed by the connection or disconnection of the sashes with the gears of the shaft by means of their sliding-bar mechanism.

To operate the shaft E, which communicates motion to the shaft D, we provide a crank handle or lever M at its projecting front end c2, said crank-arm being preferably pivotally connected to the end of the shaft, as at m, so that a catch m at the inner side of its outer end can be engaged with or disconnected from a concentric series of notches n, arranged in a face-plate N, provided upon the window-casing, this pivotal movement of the crank arm or handle lll being governed by a spring 0, projecting from the shaft E and bearing upon the pivotal connection m.

It will be understood that the crank M may be operated from and to the notched face-plate to engage with or detach from the lockingnotches therein and may be rotated in either direction to raise or lower the sashes either in a simultaneous or independent movement.

By reason of the locking connection between the plate N and the operating-handle M the sashes will be locked in any position to which they may have been adjusted whenever said sashes are in connection with the gears on the rotary shaft D, and the said mechanism will also serve to lock either or both sashes when they are in normal closed position whenever the rack-sections t' or lare brought into contact with the gears F. rl`l1e locking operation of the handle M is virtually automatic by reason of its spring-controlled pivotal connection with the shaft E. It will furthermore be noted that the arrangement of the mechanism is such that the sashes can only be operated from the inside of the window, no operation of the mechanism from the outside being possible.

Our improvements are especially adapted for application to single window-sashes-such as are used in street and railroad cars, boats, &c.and in connection with such single sashes the locking-bars, with their operating-levers and rack-sections, such as are used in a window embodying an upper and lower sash, may be dispensed with, it being only necessary to have the gears F upon the shaft D normally engaged with the Vertical rack-bars, so that the sash can be raised or lowered by movement of the handle M and locked. in any position to which it may be adjusted.

Having fully described our invention, we claim as new and desire to secure by Letters Patentl. An improved windowsash mechanism, comprising a rotary shaft arranged with rcspe'ct to the sash and carrying gears, vertical rack-bars carried by the sash, and adapted to be engaged by said gears, the relative arrangement being such that said rack-bars terminate at a point beyond connection with the gears when the sash is in normal position, in combination with a slidable bar carried by the sash and provided with a rack-section adapted to be brought into connection with the gears upon the rotary shaft and into alinement with the vertical rack-bar upon the sash, and means for operating said bars carrying the rack-bar section, substantially as and for the purpose set forth.

2. An improved window-sash mechanism, comprising a rotary shaft arranged with respect to the sash and provided with gears, vertical rack-bars carried by the sash and adapted to be engaged by said gears, the relative arrangement being such that said rack bars terminate at a point beyond engagement with the gears upon the rotary shaft'when the sash is in normal posit-ion, bars slidably mounted in the end crossbar of the sashframe and carrying rack-sections adapted to be brought into connection with the gears upon the rotary shaft and into alinement with the vertical rack-bars upon the sash, and an IOO IOS
